Some malware can steal private keys for bitcoin wallets allowing the bitcoins themselves to be stolen.As later blocks are chained after it, the work to change the block would include redoing the work for each subsequent block.A Bitcoin miner with just over half the network hash rate can play a more profitable and less risky game than double spending or denial of service.

If a majority of computing power is controlled by honest nodes, the honest chain will grow fastest and outpace any competing chains.
